Specification of Letters Patent.

Application filed June 9, 1916.

To all whom it may concern:

Be it known that I, EARL A. KNownR, a citizen of the United States, residing at ackwaukee, in the county of Marquette and State of lVisconsin, have invented new and useful Improvements in Priming Devices, of which the following is a specification.

This invention relates to priming devices for multiple cylinder internal combustion engines such as are now commonly employed in aut(' mobiles. motor boa ts, aircraft and the like. the object in view being to provide adevice of the character referred to which is accessible to the driver without leaving his seat and by means of which all of the cylinders of the engine may be quickly and simultaneously primed for starting purposes, particularly in cold weather, the device being of such a character that it may be operated by simply pushing and pulling upon a handle located in rear of the dash of t 1e machine.

lVith the above and the invention consists other objects in View, in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings Figure 1 is a vertical longitudinal section through a priming device embodying the present invention, showing the normal or non-priming position of the plunger.

Fig. 2 is a similar view showing the plunger in its priming position.

The

of all the cylinders of th may be connected to the cylinders by means of tubular extensions or nipples 2 which 7 occupy the positions now usually occupied by the priming cups.

he casing 1 is preferably square or rectangular in cross section and mounted therein is a plunger 3 which fits snugly within the casing l and corresponds in cross sectional shape thereto so as to prevent the plunger from turning within the casing, and thereby insuring the proper registration between the measuring chambers of the plunger and the connections 2 which lead to the cylinders of the engine. The plunger 3 is movable longitudinally within the easformed with a plurality of measuring chambers 4 extending there- ,means of a partition wall rnrnnr onnrcn.

through from top to bottom, each of said chambers .ibeingso proportioned as to con tain an amount of priming liquid suficient for each combustion chamber of the engine. The measuring chambers 4 extend entirely through the plunger 3 from top to bottom andin the position illustrated in Fig. 1, the upper extremities of the chambers 4 register with ports 5 inthe bottom of a distributing chamber 6 which is located at the top of the casing 1 and which contains a supply of niming liquid delivered thereto by means of a feed pipe 7 leading from an elevated source of supply 8 such as a tank which may either consist of the fuel tank of tie car or an auxiliary tank provided specially for priming purposes.

The ports 5 are located out of 1, the measuring chambers 4 are in line with position shown in Fig. 2, the chambers 4 register with the ports 9 and the priming liquid then passes to the several cylinders of the engine. When the plunger 3 is returned to the position shown in Fig. 1, all communication is cut off between the measuring chambers 4 and the connections 2 thereby rendering the device safe in use.

The means for operating the plunger rod 10 which is fas- 11 in one end 0 the casing 1. The plunger rod 10 passes through an opening in the dash where it is provided with a suitable head or handle 12.

e opposite portion of thecasing 1 is exd sufiiciently' to form a compartment 13 divided from the main compartment by 4 formed with projecting A coiled expansion spring 17 surrounds the stem 16 and is located in the compartment 13, one end of said spring bearing against a disk-shaped collar 18 fast on the stem 16. he spring serves to return the plunger 3 to a positron where communication is cut ofl with the connections 2 leading to the engine. The partition wall 14 prevents leakage into the spring compartment 13.

with outlet pipes in 001 12 is then released whereupon the spring 17 serves to return the plunger to its initial cutting oif all CODllDllIllCt-tt-lOD and position,

liquid to the engine cylinteed of priming ders.

I claim 7 A priming device for multiple cylinder internal combustion engines, comprising a casing extending lengthwise of the battery of cylinders above the same and formed imunication with the engine cylinders, said casing being also formed with a distributing passage extending longitudinally of the top oi said casing Copies of this patent may be obtained for five cents each, by addressing the uring chambers adapted to move and having ports leading into said casing and out of vertical alin'ement with the outlet pipes, said distributing passage being in communication with a source of supply for the priming agent, a plunger movable longitudinally within said casing provided with a stem and formed with a plurality of measinto and with the said ports and also into and out of registry with the said pi pes, means for operating said plunger including a spring and a partition in said casing having a guide opening for the plunger stem and iorming a separate spring housing compartment.

In testimony whereof I a'li ix my ture.
